Unable to name volume when formatting

I am trying to use Paragon NTFS 9.5 to format a hard drive using Disk Utility and I am selecting NTFS format from the list. When I do this I am unable to enter a volume name for the drive. When I use any other filesystem there is no problem.
I was wondering if this was just me or if there is a bug in the software.
I previously installed a trial of version 9.01 in case that makes a difference.
